64排螺旋CT对主动脉夹层动脉瘤的诊断价值

Clinical Value of 64-multidetector Spiral CT in Diagnosis of Aortic Dissection Aneurysms

目的:探讨64排螺旋CT对主动脉夹层动脉瘤(ADA)的临床应用价值。方法:对在笔者所在医院住院治疗并经临床最后确诊的27例主动脉夹层动脉瘤患者的病例资料进行回顾性分析,全部病例均于确诊前行64排螺旋CT血管造影检查。CT检查图像由影像科心胸组两位有经验的医师进行非双盲阅片。结果:全部病例CT诊断结果均与临床最后诊断结果相符,其中26例清晰显示ADA的范围及分型、真假腔、内膜片等病变的细微结构显示良好。结论:64排螺旋CT血管造影结合图像后处理技术,可清晰显示夹层动脉瘤的起始和终结部位及破裂口位置,对主动脉夹层动脉瘤有重要应用价值。

Objective：To evaluate the clinic usefulness of 64-multidetector spiral CT in diagnosis of aortic dissection aneurysms （ADA）. Methods：Retrospective analysis on 27 patients of aortic dissection aneurysms which were confirmed by clinical treatment. All cases were examined by vascular imaging of 64-multidetector spiral CT before clinical treatment. Results：The CT diagnosis of all patients conform with clinical diagnosis. The range and classification in 26 patients were displayed well. The true lumen,false lumen,intimal flap and other minute structure of dissecting aneurysm in these patients were showed satisfactorily. Conclusion：The range and broken mouth of aortic dissection aneurysms were displayed very well by vascular imaging of 64-multidetector spiral CT, and it is very useful in diagnosis of ADA.
